Using the Quick Test Feature
8.2 Introduction to Quick Test
Using Quick Test it is possible to use the CT Analyzer as a versatile multimeter
with included power source or to perform polarity checks using the CPOL
polarity checker from OMICRON.
Possible fields of application for Quick Test are:
• Quick and easy resistance measurement, e.g. for wiring checks on the
secondary side of CTs.
• Quick voltage ratio checks for VTs.
• Measurement of burden values, e.g. to determine the new burden value after
changes of the relay equipment. This allows the re-calculation of the CT test
results for the new burden value by the
CT Analyzer and thus makes it
unnecessary to run an additional CT test in order to determine the behavior
of the CT with the new burden.
• Quick wiring checks using the CPOL polarity checker from OMICRON. Using
the CPOL in combination with the specific test signal provided by the
CT Analyzer ’s Quick Test feature you can check a series of test points (e.g.,
the connecting terminals of the burden wiring) for correct polarity.
The user interface of Quick Test consists of two test cards, the CT-Quick card
containing the measurement parameters and the Results card showing the
results of the measurement. Figure 8-1 shows the test cards for a resistance
measurement as an example.

Note: For a general description of the CT Analyzer user interface and basic
procedures how to operate the CT Analyzer and the Quick Test tool, please
refer to chapter 5 on page 59.
To select a measurement type, use the cursor key to move the cursor to
the Measurement Type field in the CT-Quick card and then press the
corresponding soft key of the measurement type.
